The fillet yield (100% x fillet weight ÷ round weight) of Dover sole (Microstomus pacificus) caught off central and northern California was examined with respect to fish total length and depth of capture. The yield from Dover sole caught at depths greater than 458 m was not related to fish length. However, the yield from fish caught at shallower depths was correlated with fish length; the maximum yield was obtained from fish 40‐42 cm long. Fillet yield was substantially lower for fish larger than 42 cm. A comparison of the yields of shallow‐ and deep‐caught fish showed that shallow‐caught fish had a 4.1% higher yield.
